Description

  The present disclosure relates generally to conformable adhesive articles that can be attached to or adhered to a substrate and that can be removed from the substrate without damaging the substrate. The present disclosure also generally relates to methods of making and using such adhesive articles.

  Innovative Command® Adhesive Strip products are stretch-removable adhesives that hold firmly to a variety of surfaces (paint, wood, and tiles, etc.) and can be removed cleanly without holes, marks, or sticky residues It is a strip product group. These products are generally useful for bonding to various surfaces or substrates for numerous applications.

  Generally, these products include a stretch release adhesive composition disposed on a tape or other backing. Stretch-peelable adhesives are high performance pressure sensitive adhesives that combine strong holding power with clean removal without surface damage. Stretch-peelable adhesive products are used to make structures such as hooks (for holding paintings or clothing items) or other decorative or practical elements such as articles that adhere firmly to a surface (adherend). It is designed to be cleanly removed when it is torn off a small angle from the surface. A clean removal aspect means that no tacky and/or unsightly residue remains on the surface after the stretch release adhesive has been removed, and no damage to the surface occurs during the removal process. During the stretch peel removal process, the adhesive layer typically remains adhered to the tape backing as the backing is stretched, but peels from the surface (adherent).

  The inventors of the present disclosure have recognized that existing adhesive products can be improved or enhanced by improving their conformability to the substrate or surface to which they are attached, attached and/or mounted. .. In some cases, improving the conformability allows the adhesive article to carry a greater weight. In some embodiments, the improved conformability allows the adhesive article to be used on new surfaces (eg, cinder blocks). In some embodiments, improved conformability increases or improves product performance on certain surfaces (eg, rough or textured surfaces such as wallpaper, drywall, etc.).

  The inventors of the present disclosure have recognized that increasing the conformability of an adhesive article increases or improves performance. The inventors of the present disclosure have found that providing an elongate release layer that separates from the shape-flexible backing layer during the removal process increases the conformability of the adhesive article while maintaining the non-damaging characteristics of the product. It was also recognized as a new and effective method of.

Peelable layers and films:
The peelable layers and/or films that can be used in the structures described herein can be of any suitable structure. For example, the peelable layer or film can be in the form of a foam, film, or combination thereof, having any suitable thickness, composition, and opacity or transparency. The peelable layer and/or film can be a single film layer, a single foam layer, a plurality of film layers, a plurality of foam layers, a plurality of foam and film layers, and/or a single film layer. It can be one adhesive layer or a plurality of adhesive layers.

  For example, a multi-layer structure, including a film layer bonded to a foam layer, may include, for example, coextrusion of the film and foam layer, comolding, extrusion coating, adhesive composition bonding, pressure bonding, heat bonding, And may be formed using any suitable mechanism such as combinations thereof. Useful adhesive compositions for bonding the film layer to the foam layer include the adhesive compositions described herein. If it is intended to stretch only one of the polymer film or the foam layer of the multi-layer backing to achieve debonding, that layer has sufficient physical properties to achieve its purpose, and Must be thick enough.

  The peelable layer and/or film can be selected to have suitable mechanical properties for use in the stretch release adhesive tape. For example, the stretch-releasable layer and/or film may be selected to be capable of being stretched (stretched) by at least 50 percent in a first direction (eg, the longitudinal direction) without breaking. That is, at least one dimension, such as the length of the peelable layer and/or film, can be increased by at least 50 percent by elongation without breaking. In some embodiments, the peelable layers and/or films can be stretched at least 100 percent, at least 150 percent, at least 200 percent, at least 300 percent, at least 400 percent, or at least 500 percent without breaking. .. The peelable layers and/or films can often be stretched up to 1200 percent, up to 1000 percent, up to 800 percent, up to 750 percent, or up to 700 percent without breaking. These relatively high elongation values facilitate stretch release of the adhesive article after it has been adhered to the object and/or substrate.

  The Young's modulus of the peelable layer and/or film can be an indicator of the resistance of the peelable layer and/or film to stretching. In certain embodiments, the peelable layer and/or film has a Young's modulus of 75,000 psi (about 520 MPa) or less, about 50,000 psi (about 345 MPa) or less, 25,000 psi (about 170 MPa) or less, 10,000 psi. (About 70 MPa) or less, 5,000 psi (about 3.4 MPa) or less, 1,000 psi (about 7 MPa) or less, or 500 psi (about 3.4 MPa) or less. For some peelable layers and/or films, such as those containing poly(alkylene) copolymers described below, the Young's modulus is often in the range of about 10 MPa to about 75 MPa. For example, the Young's modulus can be in the range of 20-75 MPa, in the range of 20-60 MPa, in the range of 20-50 MPa, or in the range of 25-50 MPa. Young's modulus can be measured, for example, using the method of ASTM D790-07 or ASTM D882-02.

Encourage things. Preferably, the foam layer is capable of achieving an elongation of about 50 percent to about 600 percent (ie, the foam layer is at least 50 percent to 600 percent extensible). The elongation at break is preferably large enough so that the peelable layer and/or film remains intact during removal of the adhesive tape from the substrate to which it was adhered.

  The foam peelable layer and/or film may be selected to optimize properties such as conformability and elasticity. The conformable and resilient polymer foam is well suited for applications where the adhesive article will be adhered to a substrate having surface irregularities. The foam layer is at least about 2 pounds per cubic foot (pcf), at least about 6 pcf, at least about 8 pcf, or at least about 12 pcf and has a density of less than about 30 pcf, less than about 25 pcf, or less than about 15 pcf.

  The polymeric film backing layer may be in various forms including, for example, monolayer or multilayer films, porous films, and combinations thereof. The polymer film may contain one or more fillers (eg calcium carbonate). The polymer film may be a continuous layer or a discontinuous layer. The multilayer polymeric films are preferably integrally bonded to each other in the form of composite films, laminated films, and combinations thereof.

  In some embodiments, the peelable layers and/or films are typically rubbery materials and may be slightly tacky. The pressure sensitive adhesive layer can be disposed adjacent to at least one major surface of the stretch releasable layer and/or film. In many embodiments, a first pressure sensitive adhesive layer is disposed adjacent to the peelable layer and/or the first major surface of the film and the second pressure sensitive adhesive layer is peelable. Located adjacent to the second major surface of the layer and/or film. The second major surface of the peelable layer and/or film is the surface opposite the first major surface. As used herein, the term "adjacent" with respect to a pressure sensitive adhesive layer and a backing layer, means that the pressure sensitive adhesive layer is in direct contact with the backing layer, or one or more. It is separated from the backing layer by an intervening layer. That is, each pressure sensitive adhesive layer is directly or indirectly adhered to the backing layer. Exemplary intervening layers include, for example, a primer layer or a layer produced by a priming process.

  The peelable layer and/or film may be subjected to a priming treatment before being placed adjacent to the at least one pressure sensitive adhesive layer. The priming tends to increase the adhesion between the peelable layer and/or film and the pressure sensitive adhesive layer. This increased adhesion is often desirable for stretch release adhesive tapes. That is, in embodiments of the present disclosure designed for stretch release, the adhesion of the pressure sensitive adhesive layer to the peelable layer and/or film is stronger than the adhesion of the pressure sensitive adhesive layer to the substrate. Is usually desirable. Any suitable priming treatment known in the art can be used. For example, the priming treatment can include chemical primer composition treatment, corona discharge or plasma discharge treatment, exposure to electron beam or ultraviolet radiation, acid etching, or a combination thereof.
